..74 @rre To the accomplishment of this object and such others as mayhereinafter appear the features of the invention relate to certain constructions, arrangements and methods of manufacture hereinafter described and then set forth broadly and in detail in the ap pended claims `which possess advantages readily apparent to those skilled in the art.

While the invention may be utilized to connect various components of an article together, I have selected an insole and the manner of its connection with th( shoe upper and welt of a welt shoe for the pur pose of illustntion as it shows the invention in its best form at resent devised.

The various features of) the present invention will be readily understood from an inspection of the accompanying drawings in which',

Fig. 11'.' is a perspective, partly in. section, of the finished shoe embodying the features of the present invention.

In the illustrated embodiment of the 1nvention an insole 1 is of furcular slashes 2 whichare formed normal to one face of the insole along the peripheral margin thereof. These furcular slashes may have any forked construction either with or without a stein, as may Je found desirable or expedient. That is, the;r ma take the form slxown'at A., or l5, or U, (Figi). It is preferred, however. to ernploy a slaslrof the type shown at (l which comprises a fork 3, having two tines el, and

provided with a series' a stem 5 connected to the fork. The insole is also rovided with a series of awl cuts 6, (Fi 6 each one of which extends parallel to tie slashed face of the insole from the edge of the insole to one of the slashes which it intersects below the surface of the insole thus separating the material of the insole bounded by the tines kl of the fork from the body portion of the insole and forming a tongue 7, (Figs. 5, G and T) integral therewith. 4 As the furcular slashes and awl cuts are formed normal to the face and edge of the insole respectively the sides of the tongues are perpendicular to the face of the insole and the top and bottom faces of the tongues are parallel. This construction produces a tongue uniform in width and thickness substantially throughout its length thus insuring a substantial piece of stock to hold the stitches. lVith this construction all danger of the tongue buckling so that it can be pulled back into the awl cut when the stitch is being set, thus permitting the thread to slip from the tongue, is obviated.

With the insole thus prepared it may be connected to a shoe upper and welt in an)7 suitable manner found desirable or expedient. Preferably a shoe upper 8 is secured in lasted position to the edge face of the insole in which position it is interposed between the insole and a welt 9 so that the edge of the upper is substantially Hush with the tread or bottoni faces of the insole and welt and with the contacting faces of the welt and upper and of the upper and edge face of the insole arranged in parallel planes normal to the face of the insole. The upper, insole and welt are connected together by a thread 10 which extends progressively along a longitudinal slit 1l, formed in the welt 9, through the welt, upper and insole, over the tongue 7 and back through the insole, upper andv welt to the slit therein. ,As shown in Fig. o' the slit 11 in the welt is formed in the same plane as the bottoms of` the tongues in. the insole. faces of the welt and insole and the free edge of the upper lie substantiallyY Hush, they form a smooth continuous surface to bear on the upper face of theoutsolejn the finished shoe (Fig. 12).

While in its broader aspects the invention contemplates preparing the insole with tongues prior to the sewing operation, it is preferred to form the tongues in the machine which connects the shoe upper, Welt and insole together. To this end the Inachine preferably is provided with a gouge 12, (Figs. Q and 3) arranged to reciprocate at right angles to the face of the insole and provided with two cutting edges one of which, the edge 13, forms the stem of the fureular slash and the other one of which,

the fork with its two the edge 14, forms tines. In order to limit the depth of the Since theI bottom slash the gouge carries a block 15 which strikes against the surface of the insole during the downward movement of the gou e, (Fi 2). After the gouge 12 forms t e slash it is withdrawmand an awl 16 is actuated in the plane of the slit 11 through the welt, upper and insole, (Fi 4 and 5). The awl cut intersects the slas below the surface of the insole and penetrates the insole beyond the juncture of the stom and fork thus forming a tongue from 'the material bounded by the tines of the fork. As shown in Fig. 4 the width of the awl is greater than the distance between the tines of the fork in order to form a clean line of demarcation between the tongue and the body portion of the sole. As the block 15 limits the downward movement of the gouge in the same manner for each succeeding slash, and as the gouge and awl operate normal to the face and edge of the insole, respectively, it will be a parent that the tongues are uniformly ormed, a result heretofore considered impossible.

As soon as the awl withdraws, a straight eye-pointed needle 17 carrying the thread passes through the awl cut formed in the welt. upper sole finally emerging through the stem of the slash above vthe surface of the insole, (Figs. 7 and 8). After the needle has passed completely through the work in the manner illustrated in Fig. 8 it is withdrawn from the work and forms a loop in the thread. During the first part of the return stroke of the needle the loop is engaged by a nose 18 formed upon an oscillating looper 19. The looper first oscillates in the directioni, of movement of the retreating needle to throw the loop over one of the tongues, (Fig. 9). Just before the thread is looped over the tngue the looper is dropped upon the tongue, (Fig. 10), and then when the needle withdraws from beneath the tongue, the looper is oscillated in the reverse direction which causes to release the thread and to wipe over the tongue and depress it substantially iiush with the surface of the sole, (Fig. 11), after which the looper is returned to is original position. The stitch is now set by drawing the thread taut over a part of the tongue close to its base.

AThose skilled in the art will readily appreciate from 'an inspection of Fig. 12 the important advance in the art of shoe making4 initiated by the present invention. A shoe embodying the features of the present invention is more comfortable to wear than welt shoes heretofore devised as the construction thereof eliminates the plastic filler between the insole and outsole and thus avoids both the possibility of the formation of the objectionable trough in the forepart of the insole and also the presence of the marginal feather or abutment which frequently causes the looper discomfort. It is also more economical to manufacture as a large number of the operations heretofore considered essential in the formation of welt shoes are eliminated, particularly those operations formerly employed to prepare the insole for the sewing operation and to fill the cavity between the inner and outer soles. AIt will readily be apparent to those skilled in the art that the shoe of the drawings is more exible than the shoes made by the Goodyear process since the stiff rib for holding the stitches is eliminated. This flexibility is further increased by the stems of the furcular slashes formed in the insole. For many reasons obvious to those skilled in the art the shoe illustrated in Fig. 12 is more durable than the welt shoes heretofore devised. One reason for this is that the inseam stitches of the improved shoe are arranged substantiall-y in the lane of flexure of the shoe` while in the ormer welt shoe the inseam stitches were not so arranged and consequently were subjected to strain every time the shoe flexed in walking.

)Vhile it is preferred to employ the specific construction, arrangement and method of manufacture shown and described, it will be understood that this specific construction, arrangement and method of manufacture is not essential nor is the conjoint use of all the features of the invention essential except so far as s ecified in the appended claims and it may e varied or modilied without departing from the broader features of the invention.

It will also be apparentto those skilled in the art that the present inventioii is useful] in the manufacture of other kinds of shoe than welt shoes, therefore,
